exhaust like sound ...
Today I was driving to work on the highway.
I always have heard, since I have owned it, a clicking sound that is variable and in sync with the rpms. I start to hear it as you let off the accelerator at speeds above 30ish
Today, while driving down the highway, I heard a sudden increase in the noise.
The noise is still there and more promininent than ever. It is noticeable while accelerating at around 1300 rpms.
I am guessing a exhaust gasket between and up pipe and someting else or something else. I can't notice it at idle and can't see anything different.
I don't have gauges and don't know what my egts are at, but I am not towing anything and I have a 3" dp and a tymar intake. No smoke coming out of exhaust.
Ideas?

I can hear it only in the cab.
No CEL lights, no nada. The only change I observe is the noise. At around 1300rpms I start to notice it sounds like a big block with the exhaust manifold is blown.

the sensor and it's tube is what gets clogged. the valve in the turbo can stick, but you would hear a hissing sound if that happened. i would give it a thorough visual inspection all around the manifolds, uppies, turbo and down pipe. look for soot indicating a leak.

Maybe it is my fear that doesn't want an internal click.

You unplugged the EBPV and did you wire it open? Mine fluttered when I unplugged it and I noticed the noise on acceleration. I was told to wire it open. I just pluged it back in until I decide on whether to gut it or put in a switch to make an exhaust brake.

there shouldnt be a need to wire it open, if its unplugged then it shuoldnt move, try grabbing the rod and see if its loose, you shouldnt be able to move it. if you can then the spring is busted inside and you need to wire it open
